The Marvel Knights category includes characters only from the main Marvel Universe (Earth-616) to prevent an overload of all the various characters' incarnations from alternate universe stories. If they are from an alternate universe or dimension, but they have spent most of their adventures of interest in the Marvel Universe or interacting with the Marvel Universe (e.g. characters like Longshot and Bishop would be in the X-Men category), include them here. Just as the X-Men Category includes both the X-Men and their friends and enemies, this category should be for the Knights themselves, and the characters they've commonly interacted with during the course of their stories under the Marvel Knights imprint. The main Marvel Knights are Daredevil, the Punisher, Black Panther, Elektra, Blade, Ghost Rider, Black Widow, Shang-Chi, Moon Knight, Cloak and Dagger, Iron Fist, Luke Cage, and Spider-Man. Others include Bishop, Crystal, Medusa, Shanna, and Wolverine. Just because Spider-Man was "knighted" doesn't mean every Spider-Man character belongs in this category. For a good sense of what characters are appropriate for this category, check out the Marvel Knights Encyclopedia (Marvel Encyclopedia Vol. 5), and the Offiical Handbook of the Marvel Universe: Marvel Knights 2005.
